DC - distribution and protection components Green protect - DC Introduction Photovoltaic systems are composed by photovoltaic panels, cables, fuses, switches, overvoltage arresters and power inverter. Photovoltaic panels utilise the power of sun light to converters photons to DC current. Electricity generated by solar panels is then fed into a power inverter that converts DC current to AC current. gPV fuse has been developed to protect cable and panel against "reverse" overcurrent. ETITEC B, C-PV series of over voltage surge protective devices has been developed to protect against direct...

ETITEC B T12 PV series of overvoltage surge protective devices has been developed to protect against direct and indirect discharges and is intended to protect photovoltaic systems. The circuit topology consist of three varistors stages each protected by a thermal disconnection device. - optical indication of faulty device (green ok, red false) - remote signalisation (RC version only) - DIN rail mounting (EN 60715) - high discharge currents and high degree of protection - MOV varistor is the protective element - metal snapper, new way of mounting on DIN rail (easier, quicker) - modular...
